Why 5W20 Oil Synthetic Blend is Beneficial for My Vehicle

As a vehicle owner, I’ve always been on the lookout for ways to enhance my car’s performance and longevity. One of the best decisions I made was switching to a 5W20 synthetic blend oil. This oil type has proven to be incredibly beneficial for several reasons.

First and foremost, the viscosity of 5W20 oil is perfect for my engine’s needs. The “5” indicates its low-temperature performance, which means it flows easily during cold starts.
